Can you connect a SainSmart relay board directly to a door sensor?

  • I want to activate a 16 channel SainSmart relay board using door sensors. No special programs to be used, just want to have a relay to be on/off to indicate sensor status. Is it possible to wire the sensor directly to the relay board without using an Arduino? It may require a driver circuit but I want it to be as simple as possible. Any suggestions?
